The equation of the parabola which passes through the point (-3, -8) as described and has x-intercepts -7 and -4 as described is; y = -2 (x + 4) (x + 7).

It follows from the task content that the equation of the parabola whose x-intercepts are -7 and -4 and has the point, (-3, -8) on it be determined.

Since the equation of a parabola in the factored form usually takes the form;

y = a (x - f) (x - g) in which case when f and g are x-intercepts of the parabola.

Therefore, we have; y = a (x - (-4)) (x - (-7))

y = a (x + 4) (x + 7)

Hence, to find the value of a, we set y = -8 and x = -3 so that we have;

-8 = a (-3 + 4) (-3 + 7)

-8 = 4a

a = -2.

Therefore, the equation of the parabola is; y = -2 (x + 4) (x + 7).

Answer: To calculate the annual depreciation expense of the equipment using the straight-line method, we need to first determine the depreciable cost of the asset, which is the cost of the asset minus its estimated residual value.

Depreciable Cost = Cost of asset - Estimated Residual Value

Depreciable Cost = $212,000 - $14,000

Depreciable Cost = $198,000

Next, we can use the following formula to calculate the annual depreciation expense:

Annual Depreciation Expense = Depreciable Cost / Useful Life

Annual Depreciation Expense = $198,000 / 15 years

Annual Depreciation Expense = $13,200 per year

Therefore, the annual depreciation expense of the equipment using the straight-line method is $13,200 per year.

Answer:

15/13

Step-by-step explanation:

Convert to improper fractions: 5/2 divided by 13/6

Multiply the first term by reciprocal: 5/2 * 6/13 = 30/26

Simplify: 30/26 can become 15/13

\( = 2 \frac{1}{2} \div 2 \frac{1}{6} \)

\( = \frac{5}{2} \div \frac{13}{6} \)

\( = \frac{5}{2} \times \frac{6}{13} \)

\( = \frac{30}{26} \)

\( = \frac{30 \div 2}{26 \div 2} \)

\( = \frac{15}{13} \)

\(\color{hotpink} = 1 \frac{2}{13} \)

\(\therefore\color{olive}2 \frac{1}{2} \div 2 \frac{1}{6} = \color{hotpink} \frac{15}{13}\color{olive} (or) \color{hotpink}1\frac{2}{3} \)

Answer:

C

Step-by-step explanation:

- (\(\frac{28x+12}{8}\) ) < 6x - 30 ( multiply both sides by 8 to clear the fraction )

- (28x + 12) < 48x - 240 ← distribute parenthesis by - 1

- 28x - 12 < 48x - 240 ( subtract 48x from both sides )

- 76x - 12 < - 240 ( add 12 to both sides )

- 76x < - 228

divide both sides by - 76 reversing the symbol as a result of dividing by a negative quantity.

An equivalent inequality to the given \(-4(x + 7) < 3(x - 2)\) is \(7x > -22.\)

To find an equivalent inequality, we can start by simplifying the given inequality and then make adjustments to preserve its truth.

Let's simplify the given inequality step by step:

\(-4(x + 7) < 3(x - 2)\)

Expanding both sides:

\(-4x - 28 < 3x - 6\)

Grouping like terms:

\(-4x - 3x < -6 + 28\)

Simplifying:

\(-7x < 22\)

To maintain the direction of the inequality, we need to multiply both sides by -1.

However, when we multiply or divide both sides of an inequality by a negative number, the direction of the inequality is reversed.

Therefore, we need to flip the inequality sign:

\(7x > -22\)

Hence, an equivalent inequality to the given \(-4(x + 7) < 3(x - 2)\) is

\(7x > -22.\)

At equilibrium price and quantity, the answer is 1. The quantity supplied equals the quantity demanded.

This means that the market is in a state of balance, where the quantity of a good or service that producers are willing to supply is exactly the same as the quantity that consumers are willing to buy. As a result, there is no excess supply or excess demand, and the price of the good or service is stable.

The unadjusted cost of goods sold for the year is calculated by subtracting the ending inventory from the sum of beginning inventory and purchases. The formula is as follows:

Unadjusted Cost of Goods Sold = Beginning Inventory + Purchases - Ending Inventory

Without knowing the values for beginning inventory, purchases, and ending inventory, we cannot compute the unadjusted cost of goods sold for the year.

5. Given that the $70,000 ending balance in Work in Process includes $24,000 of direct materials, we can calculate the missing information as follows:

Direct Labor = Total Work in Process - Direct Materials - Overhead
Direct Labor = $70,000 - $24,000 - Overhead

Without knowing the value for overhead, we cannot compute the direct labor cost. However, we can rearrange the formula to solve for overhead:

Overhead = Total Work in Process - Direct Materials - Direct Labor
Overhead = $70,000 - $24,000 - Direct Labor

Without knowing the value for direct labor, we cannot compute the overhead cost.

a) The dimensions so that the total enclosed area is as large as possible is  W = 333.33 and L = 500.

b) The maximum area is obtained as 333330 square yards.

What is area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

a) To find the dimensions so that the total enclosed area is as large as possible, we can use the fact that the two corrals share a side, which means that we can write the total perimeter as -

2L + 3W = 2000

where L is the length of one corral and W is the width of both corrals. Solving for L, we get -

L = 1000 - 1.5W

The total enclosed area is the sum of the areas of the two corrals -

A = LW + LW = 2LW

Substituting the expression for L, we get -

A = 2(1000 - 1.5W)W =

A = 2000W - 3W²

To find the dimensions that maximize the area, we can take the derivative of A with respect to W and set it equal to zero -

dA/dW = 2000 - 6W = 0

Solving for W, we get -

W = 2000/6 = 333.33

Substituting back into the expression for L, we get -

L = 1000 - 1.5(333.33) = 500

Therefore, the dimensions that maximize the total enclosed area are 500 yards by 333.33 yards.

b) To find the maximum area, we can substitute the values of L and W that we found into the expression for A -

A = 2(500)(333.33)

A = 333330

Therefore, the maximum enclosed area is 333330 square yards.

The limit lim(x approaches 0) (cosec(2x) - x*cosec³(x)) is undefined.

We have,

To evaluate the limit of the expression as x approaches 0, we can simplify the expression first.

The expression is given as lim(x approaches 0) (cosec(2x) - x cosec³(x)).

Using trigonometric identities, we can rewrite cosec(2x) as 1/sin(2x) and cosec³(x) as 1/(sin(x))³.

Substituting these into the expression,

We get lim(x approaches 0) (1/sin(2x) - x (1/(sin(x))³)).

Now, let's evaluate the limit term by term:

lim(x approaches 0) (1/sin(2x)) = 1/sin(0) = 1/0 (which is undefined).

lim(x approaches 0) (x (1/(sin(x))³))

= 0 (1/(sin(0))³)

= 0 x 1/0 (which is also undefined).

Since both terms of the expression are undefined as x approaches 0, we cannot determine the limit of the expression.

Therefore,

The limit lim(x approaches 0) (cosec(2x) - x*cosec³(x)) is undefined.
